SD Cards support encryption and content protection that is indicated by the word ‘Secured’. A user can ensure that the data he has stored are secured unless and until he takes the necessary steps to unprotect them. Thus, SD cards offer the benefit of ‘write protection’. So, fears of accidentally losing or changing data can be eliminated by using these cards. Still, these are used for regular storage due to their small size and fast transfer rate.

Mini SD and Micro SD Cards are the miniature variations of the SD Card. They were introduced with dramatically smaller footprints: the former in 2003 and the later in 2005. Electrically, as well as software compatible, both these variations fit into a regular SD slot via an adapter. One of the great things about these cards is that the user can choose the size, as well as the quantity to have on hand, … Read the rest

Negroponte and his team set out to build a $100 laptop so that people and especially children all around the world could be online. Although the project now looks more like it will be $175 per laptop it is still a very viable concept.

Currently we have 6.6 billion people on the planet and 2 billion of them are children. Only the children in the first world countries have computers or laptops. More and more children will have access to the Internet in the future, but right now most children do not. If we are to bring up the entire world we need to start with the children and get them use to using computers.

If not they may be left behind as the world moves forward and it may cause them to have economic hardship throughout their lives. One laptop per child or OLPC is a great concept. There … Read the rest

Have you heard of “Zink”? No not Zune, Zink. Well, you may hear of this a lot in the not so distant future. Zero Imaging, or as it is referred to as zero ink (ZINK), is a new technology that is literally inkless. It is creating the future of digital printing. You will be able to produce high quality prints and photos without a ribbon or ink cartridge. So how do they do it? What is their secret?

The secret is their patented paper. This technology houses dye crystals inside the paper with a polymer layer outside. Before printing, the embedded dye crystals are colorless, so Zink paper looks like regular white photo paper. The Zink printer uses heat to activate and colorize these dye crystals. The printing process is now radically simple. Just add paper and press “print”. The result is high quality, long-lasting, durable, and affordable images.

The green beam is produced at a visible light frequency of 532nm and utilizes “frequency doubling” crystal technology in order to produce the bright green light. The crystal actually produces an IR (infrared) beam at around 808nm which is doubled and then collimated producing the illuminating green laser light.

Hand held pointers are a very practical form of technology, but they have also found a strong hold amongst gadget enthusiasts and laser astronomers alike. Green lasers are so useful for astronomy applications because of how bright the beam is. For years the only available form of hand held laser technology came available to produce the red laser beam. This is less bright in comparison to a green beam, so as technology improved and pointers became widely available for lower costs, the entire community of astronomy slowly but surely updated their tools to meet current standards.
